Programming manual
STM32F10xxx Flash memory microcontrollers
Introduction
This programming manual describes how to program the Flash memory of STM32F101xx,
STM32F102xx, STM32F103xx, STM32F105xx and STM32F107xx microcontrollers. For
convenience, these will be referred to as STM32F10xxx in the rest of this document unless
otherwise specified.
The STM32F10xxx embedded Flash memory can be programmed using in-circuit
programming or in-application programming.
The in-circuit programming (ICP) method is used to update the entire contents of the
Flash memory, using the JTAG, SWD protocol or the boot loader to load the user application
into the microcontroller. ICP offers quick and efficient design iterations and eliminates
unnecessary package handling or socketing of devices.
In contrast to the ICP method, in-application programming (IAP) can use any
communication interface supported by the microcontroller (I/Os, USB, CAN, UART, I
2
C, SPI,
etc.) to download programming data into memory. IAP allows the user to re-program the
Flash memory while the application is running. Nevertheless, part of the application has to
have been previously programmed in the Flash memory using ICP.
The Flash interface implements instruction access and data access based on the AHB
protocol. It implements a prefetch buffer that speeds up CPU code execution. It also
implements the logic necessary to carry out Flash memory operations (Program/Erase).
Program/Erase operations can be performed over the whole product voltage range.
Read/Write protections and option bytes are also implemented.
Table 1 lists the microcontrollers and evaluation tool concerned by this programming
manual.
